Service switch - This switch enables
the Service Engineer to temporarily
override the remote heating/hot water
controls (timer, room thermostat or
programmer) to operate the boiler for
servicing purposes. This is a
‘momentary’ or non-latching switch that
cannot be left set to ON. The boiler will
automatically revert to normal operation
when 15 minutes have elapsed since it
was last operated.
Boiler indicator lights - These 8 red
lights indicate the operating situation of
the boiler.
Boiler (heating) thermostat - Controls
the temperature of the water leaving the
boiler to the central heating system.
Operation of this control does not affect
the temperature of the hot water flowing
to the taps.
The temperature of the water leaving
the boiler to the radiators can be
increased by turning the boiler (heating)
thermostat clockwise.

About your Fuel
Grant Vortex Pro Combi boilers only
operate on Class C2 Kerosene to
BS2869:1998. You should always quote
the type of fuel you require when
ordering from your supplier.
Do not wait until the fuel runs out before
you order some more. Sludge in the
bottom of the tank may be drawn into
the fuel lines. If it is possible, switch off
the boiler when the new supply is
delivered and leave the fuel to settle for
an hour before restarting the boiler.

About your Boiler
Your Grant Vortex Pro Combi boiler is
fully automatic and when the boiler
On/off switch is set to ON, will provide
domestic hot water at mains pressure
on demand and central heating when
the hot water and heating system
controls call for it.
Your boiler may be fitted with one of the
following control options, located in a
convenient position remote from the
boiler:
• Option A Programmable room
thermostat only.
• Option B Remote timer and room
thermostat.
• Option C Remote two-channel
programmer and room thermostat.
• Option D Remote ‘wireless’ two-
channel programmable room
thermostat (with boiler mounted
‘plug-in’ receiver unit).
Whatever type of control is connected
to your boiler, it will allow you to set the
operating times of your central heating.
In the case of options A and B -
domestic hot water is available
continuously, providing the boiler is
switched on, irrespective of the heating
control settings.
In the case of options C and D - you
can set the operating times for both
heating and hot water using the heating
and hot water settings respectively on
the programmer, or wireless two-
channel programmable room
thermostat.

Boiler On/Off switch - This switches
the boiler on and off. The boiler On/Off
switch incorporates a ‘mains on’ neon;
see Figure 2, which lights when the
boiler is switched on. Please note that
the ‘mains on’ neon does not
necessarily indicate that the burner is
firing.

NOTE
When the On/Off switch is set to ON
the POWER indicator on the control
panel will light.
The boiler will not supply central
heating or domestic hot water if this
switch is set to OFF, and also the
